Abstract

Abstract: Several modifications are proposed for emergency dosimetry with different components of mobile phones. Two dosimetric techniques have been exploited, namely optically stimulated luminescence (OSL) from surface mount resistors (SMRs) and integrated circuits (ICs), and electron paramagnetic resonance (EPR) from samples of protective glass (PG). For OSL with SMRs, it was found that fading of the corresponding radiation-induced signal (RIS) is variable among the resistors of different brands and depends also on the value of the administered dose. In the case of ICs, the effect of sample sensitization with an increase in the accumulated dose was compensated by preheating the samples to some selected temperature. An approach based on the matrix spectra deconvolution of EPR spectra was proposed and tested for EPR dosimetry using smartphone protective glasses. Highlights: Modifications of dosimetry techniques with components of smartphones are discussed. Fading of OSL signals from SMRs is dose dependent. Matrix method is tested for EPR spectra deconvolution for samples of PG.
